Know Your Decimals Task Cards - Add and Subtract Money for Abracadabra Antiques

Know Your Decimals Add and Subtract Money – Abracadabra Antiques Bundle are task cards designed to provide students with opportunities to improve their skills in adding and subtracting decimals.

The context is related to a fictional store called Abracadabra Antiques which sells antiques. In the first set, students are required to add the sales from the store’s morning and afternoon sessions. In the second set, students are required to subtract the cost price of an item from the price from which it was sold, thus working out the profit for the day. The context simulates real-world examples as these calculations are common practice for any store or business in the real world.

Students will add and subtract both double and triple-digit numbers using 2 decimal places (appropriate for money). At times, a product has been sold more than once in a day so students may find themselves drawing on a variety of mental computation skills such as doubling, compensating (rounding then adjusting) and multiplying by 10 by adding an extra zero.

Although it is possible for high (super high?) achieving students to mentally calculate the totals, it is more than appropriate tor them to use the back of their answer sheet to make any calculations necessary.

While these cards are commonly used as task cards, they have also been used successfully in math centers or rotations.

This resources contains:

• 54 cards (48 task cards, 1 title card per set & a display card highlighting the selling and cost prices for the products in the Abracadabra Antiques store)
• Student recording sheet
• Answer keys
• Complete PDF and individual PNG files of the cards also included (very helpful for demonstrating an example or working through a card as a whole class)

Instructions:

• Print student sheet and provide each student with a worksheet
• Distribute the cards around the room (or allocate your desired number of cards for use in a math rotation or center). Students may start at any number and work their way through in any order, but it is helpful to remind students to write the answer in the same numbered answer box i.e., if they are on card number 12, they should write their answer in answer box number 12
